Next up: A clip of the singer repeatedly slamming her elbows into a dummy doll used for self-defense training. The caption: “I hate the word victim. I never have been and I never will be.” That video (proof positive that Lovato is the definition of #girlpower!) has racked up more than 381 thousand likes and 9,400 comments.

As if we weren’t already feeling inspired enough, the latest clip shows Lovato looking especially fierce as she boxes with straps around her torso and ankles that are attached to a machine called the Raptor. "By far one of the hardest workouts I’ve ever done!!” she wrote.
